What we now recognize as a super-group was, at the time of this 1960 session, just five young musicians of modest reputation gathering to create the debut album for a promising and already distinctive trombonist. Julian Priester seized the occasion and blew like a veteran, displaying a strong sound all over his horn, a clear melodic conception, and a talent for writing. His skills stood Priester in good stead through his tenures with Max Roach, Duke Ellington, Herbie Hancock, and Dave Holland in the ensuing decades. Like all except the late Sam Jones, he continues to function as one of jazz’s major voices today, and the straightforward, eloquent fervor of his mature work bears out the promise displayed here.
